I would reach out to Lathrop and Sons if you are looking for a heavier boot. They have a MTN Hunter wide and a newer super wide boot if you are looking for a heavy duty boot. Great guys to work with and the build quality is excellent. I wish they had the super side when I bought mine as that extra width would have really made them the perfect heavy boot. For Crispi I use the Lapponia 3 which is wide enough for me and due to the supple material feels wider than it is. I also would look at the Idaho 3 as they are supposed to have a similar last and with synthetic maybe a little more forgiving in the forefoot.
